A lieatio med December 29,1906. Serial No. 350,050.:

To'ctZZ whom it may concern.- Be it known that I, EnUARD QUAQK,.EL subject of the German Emperor, and a resident of Elberfeld, Germany, have invented certain new and useful lmprovements in Gas' Stoves, ofwhich the following is a specification. l

This invention relates to a gas stove which is especially designed -to serve as. cooking stove but which can be also used at the same time as heatingstove. I V g The improvements consist in that :1,

- the heat produced by the stovecan be easily regulated to any desired degree; and 2, the loss oflheat, which with hitherto known gas I stoves was due to the escape of imperfectly burnt gases or to the supplyof superfluous air, is effectively avoided.

The accompanying drawings show the gas stove embodying the invention. a

Figure 1 .is a sectional elevation of the burner arran ement, and Fig. 2 afplan of a gas stove wit two fireplaces, the cover of the stove being omittedto show the interior of the same; while-Fig. 3 is a sectional side view of the gas stove. Fig. 4 shows an ad justable envelop which is to be placed around the lower part of a cooking vesselinserted in the gas stove; Fig. 5 shows the way in which the single burner tubes can be closed so as touse only one or some of them in order to regulate the heat to the desired degree.

The gas stove comprises a casingl which is made of double walls with a space 2 left between themfand-closed near its bottom tion with a flue-pipe 4 which is introduced into the outer rear wall of the casing. The.

casing 1 is closed at its top by a'cover 5 which is also made of double walls and integral with the double front wall of the casing and disposed so as to leave a space 6 between its project somewhat above the cover 5 when" the latter is closed so as to insure the best bottom and the top edge of the inner side wallsof the casing and hingedly connected to the outer rear wall of the casing at 7 and counterweighted by the balance lever 8 and weight 9 so that it is always kept in balance when being opened as shown by the dotted lines at 5 in Fig-S.

The top plate 20 is fitted with two series of burner tubes 24 of which one is in communication with one gas chamber 10 and 'theLQther one with the other gas chamber 11. The top plate 20 'is somewhat inclined toward its circumference so that any soot or other impurities settling on the burner tubes 24 can gradually slide down; or be swept down, this inclination from where. they fall theninto a the bottom plate 21, so that greatestcleanliness is insured. .This burner arrangement as just described, is now placed beneath a ring plate 26 which is inserted in a corresponding opening of the base plate 3 of the casing 1, in
